Attenuating the haptic horizontal—vertical curvature illusion

In a number of experiments, blindfolded subjects traced convex curves whose verticals were equal to their horizontal extent at the base. Overestimation of verticals, as compared with horizontals, was found, indicating the presence of a horizontal-vertical illusion with haptic curves, as well as with visible curves. Experiment 1 showed that the illusion occurred with stimuli in the frontal plane and with stimuli that were flat on the table surface in vision and touch. In the second experiment, the stimuli were rotated, and differences between vision and touch were revealed, with a stronger illusion in touch. The haptic horizontal-vertical illusion was virtually eliminated when the stimuli were bimanually touched using free exploration at the body midline, but a strong illusion was obtained when curves were felt with two index fingers or with a single hand at the midline. Bimanual exploration eliminated the illusion for smaller 2.5- through 10.2-cm stimuli, but a weakened illusion remained for the largest 12.7-cm patterns. The illusion was present when the stimuli were bimanually explored in the left and right hemispace. Thus, the benefits of bimanual exploration derived from the use of the two hands at the body midline combined with free exploration, rather than from bimanual free exploration per se. The results indicate the importance of haptic exploration at the body midline, where the body can serve as a familiar reference metric for size judgments. Alternative interpretations of the results are discussed, including the impact of movement-based heuristics as a causal factor for the illusion. It was suggested that tracing the curve’s peak served to bisect the curve in haptics, because of the change in direction.     

The Coming Epoch of New Coalitions: Possible Scenarios of the Near Future

This article analyzes some important aspects of socioeconomic and political development of the world in the near future. The future always stems from the present. The first part of the article is devoted to the study of some crucial events of the present, which could be regarded as precursors of forthcoming fundamental changes. In particular, it is shown that the turbulent events of late 2010 and 2011 in the Arab World may well be regarded as a start of the global reconfiguration. The article also offers an analysis of some aspects of the global financial system that, according to the authors, notwithstanding all its negative points, performs certain important positive functions including the “insurance” of social guaranties at the global scale. The second part of the article considers some global scenarios of the World System's new future and describes a few characteristics of the forthcoming “Epoch of New Coalitions.” The article attempts to answer such questions as the following: What are the implications of the economic weakening of the United States as the World System center? Will the future World System have a leader? Will it experience a global governance deficit? Will the world fragmentation increase?     

Orthographic regularity gradually modulates saccade amplitudes in reading

The present research tested the hypothesis that variations in the orthographic regularity of word beginnings influence landing positions and amplitudes of interword saccades in continuous reading. Participants were asked to read sentences including target words of low, medium, and high frequency of initial quadrigrams that were either single‐root nouns or noun‐noun compounds. Saccades landed further into words with more regular beginnings, irrespective of whether the target was a compound word or not. Critically, the orthographic landing site effect was graded, suggesting that orthographic information continuously modulates saccade amplitude before and after the decision to move has been made.     

Dimension‐specific intertrial facilitation in visual search for pop‐out targets: Evidence for a top‐down modulable visual short‐term memory effect

In visual search for pop‐out targets, target detection is expedited when the target‐defining dimension (e.g., colour) is repeated on consecutive trials, but not (or less) when the target feature (e.g., red) is repeated (Found & Müller, 1996). The present study examined whether this dimension‐specific intertrial facilitation (ITF) is mediated by an explicit or an implicit memory of the target on the previous trial. In Experiment 1, observers had no above‐chance knowledge of the target dimension (or feature) when this information was not to be encoded and retained explicitly; yet, they exhibited dimension‐specific ITF. In Experiment 2, the nature of the ITF effect was unaffected by whatever attribute of the target was to be explicitly encoded and memorized, its dimension or feature; however, ITF was increased compared to a no‐memory control condition. In Experiment 3, ITF was not increased when observers had to determine the target dimension, but without having to maintain a memory of it during the intertrial interval. These results suggest that, although an implicit memory is sufficient for producing dimension‐specific ITF, ITF is top‐down modulable by explicit memory instructions.     

Neuropsychological differentiation of adaptive creativity and schizotypal cognition

Both creativity and schizophrenia-spectrum disorders have been associated with activation of remote semantic concepts, but this activation results in innovative output in one case and communication disturbances in the other. The present study examined the relationship between monitoring semantic information (which relies on executive brain function), creativity, and characteristics of schizotypy in an undergraduate population. Results indicate that executive function differentiates the use of semantic information in creativity and schizotypy. Specification of the balance between executive monitoring and activation of semantic information is important for determining how communication disturbances manifest, and for the measurement of creativity and schizotypy in the general population.     

Editor's Foreword

Abstract

The importance of the initial interview as an essential evaluative and therapeutic tool has been much discussed in the literature. Unfortunately, the variety of theoretical approaches as well as evaluative concepts can often seem confusing and overwhelming to the beginning psychotherapist. The purpose of this paper is to describe a comprehensive, integrative model for the initial interview. Essential theoretical constructs which encompass intrapsychic, intergenerational and interactional approaches are defined. These constructs are synthesized in a manner which transcends various theoretical models offering a more manageable, comprehensive framework in which to conduct an interview. The importance of considering therapist behaviors which promote engagement are also discussed.

Heuristics in medical and non-medical decision-making

Pairs of hypothetical medical and non-medical problems were given to 44 pediatric residents at three levels of hospital training. Each problem was designed to detect a specific heuristic-based bias in making diagnoses. Discounting, disregarding base rate, and over-confidence in contextually embedded redundant information were more evident on medical than on non-medical problems. In particular, a greater number of third-year residents disregarded base-rate information than did first- and second-year residents on medical but not on non-medical problems. On medical problems, a greater number of first-year residents expressed greater confidence in redundant information that was contextually embedded than in information that was presented in a listed format. Over one-third of the residents confused prospective and retrospective probabilities; three-fourths showed evidence of augmentation; virtually all residents expressed greater confidence in a diagnosis based on redundant rather than on non-redundant listed information. These latter effects were consistent across training level and occurred on both medical and non-medical problems. The results are discussed in terms of prototype theory and the nature of medical training.     

Psychology in the Czech lands: Bohemia,Czechoslovakia, and the Czech Republic

The article provides a comprehensive review of Czech psychology—its history and its current state. It enumerates significant psychologists who were Czech, born in Bohemia or who were instrumental for the development of psychology in the region. The article also enumerates Czech psychological associations along with their main representatives, journals, and academic facilities involved in education and research in psychology. It is pointed out that the origins of psychology as a science are in the Central Europe—the first laboratory of W. Wundt was in Leipzig, Germany; S. Freud was born in Bohemia, in the Moravian city of Příbor and he practiced in Vienna, Austria. The Czech capital Prague will also become the capital of the psychological science in 2020 when it will be hosting the 32nd International Congress of Psychology (ICP 2020).
